strip breakage

Large quantity of rejected products involving edge crack and strip breakage are prone to occur in hot and cold rolling of the oriented silicon steel sheets due to high brittleness of the steel caused by its high silicon content.

取向硅钢含硅量高，钢质脆性大，在热轧和冷轧过程中容易产生大量边裂及断带轧废。

Those troubles can not only greatly affect the improvement of productivity of the ZR mill, but also severely damage the rolling equipments, so how to solve the problems of strip breakage and roll wind-up has long been an important subject of our research work.

这不仅会严重影响轧机生产率的提高，而且还会损坏设备。因此，长期以来，如何解决断带与缠辊的问题已成为重要的研究课题。

Measurement and analysis on strip breakage and roll wind-up on ZR mill

However, when the content of Si is about 10%, its plasticity is poor, particularly in cold-rolling process. The poor plasticity led to the strip breakage in rolling process and it reduced the rate of finished products.

然而，4004Al-Si合金，由于含Si量在10%左右，塑性差，特别是冷轧性能差，进而导致轧制过程中易产生断带，成品率低。

Strip breakage happened very often in the annealing assembly line at the silicon steel workshop of Wuhan Iron& Steel Corp.

武钢硅钢厂退火生产线经常发生因带钢跑偏造成断带事故。

Strip breakage and roll wind-up frequently occur on the ZR 20 when rolling the fragile stock with severe quality problems such as worse shape, serious surface and edge defects.

森吉米尔轧机（ZR20）在轧制板形不好、板面和边部有严重缺陷的脆性原料时，经常出现的生产故障是断带缠辊。
